초록

PURPOSES : The objective of this study is to analyze and evaluate the behavior of orthotropic steel bridge deck pavement using three-dimensional finite element analysis and full-scale wheel load testing.
METHODS : Since the layer thickness and material properties used in the bridge deck pavement are different from its condition, it is very difficult to measure and access the behavior of bridge deck pavement in the field. To solve this problem, the full-scale wheel load testing was conducted on the PSMA/Mastic bridge deck pavement and the deflection of bridge deck and horizontal tensile strain on top of pavement were measured under the loading condition. Three-dimensional finite element analysis was conducted to predict the behavior of bridge deck pavement and the predicted deflection and tensile strain values are compared with measured values from the wheel loading testing.
RESULTS : Test results showed that the predicted deflections are 10% lower than measured ones and the error between predicted and measured horizonal tensile strain values is less than 2% in the critical location.
CONCLUSIONS : The fact indicates that the proposed the analysis is found to be accurate for estimating the behavior of bridge deck pavements.
